Application filed May 26, 1924, Serial No. 716,035.

To a-ZZ whom if may concern Be it known" that I, lViLLL-mr S'rnWARr lineman, a vcitizen of th'e A"United States, Yand resident of Montevideo, in the county Vof Chippewa and State of Minnesota, have invented certain neiv and useful Improvements in Grease Cups, of vwhich the following is a'specificationf n h/Ivyinvention is an improvement in grease oups, and Consists inthe constructions,v comv4b inations and arrangements herein described and claimed.

An object of the invention is to provide a i vvthe interior of thel body 1. The cap 2 slidwhich' can be filled in a relatively 'short time simple, vreliable and, efficient grease cup and` Which affords facilities for exerting l,pressure on the contents thereof `ivhen theV cup has been completely filled until a considerable" quantity of the lubricant there- 2O' vvithiuhas been ejected therefrom.A

' Ajfurthe'r object ofthe invention is to provide a grease cup of the "character described Which isconstructed in such manner s that the necessity of threadedly engaging' the separableparts of the cup with each j other in "order to prevent 'spilling or Waste of the' contents off the cup is obviated.`

A still further object ofl the invention is n jto provide a grease cupwhich affords facilities fonholdinga relatively largequanfit-y Vof lubricant when the cup is of a given p size.'

A4 still vfurther object of the invention is j to providea grease cupof the character de- `,scribed which includes a body and a removable cap' connected togetherso that the cap cannotbe completely detached from the lbody accidentally.

K Other objects and advantages will be ap- 4:0A parent vfrom theyf'ollowing description, considered vin conj y 1 ing dra\vings,`in \vhich- Figure l is a side elevation of a grease `Ycupiembodying the invention,

Figure" 2 is a central fvertical section jthrough the cup, Figure 3 is a section along the line ,3-3

of Figure Al, and

i Figure 4L is a section along the line t-4 5 0 Aofl'igure 2,. and Figure 5 is a relatively reduced side elevation showing a stick of lubricant Which ishadapted to be used in the' cup` with a niece severed from the body ofthenstick for ajminsertion in the cup. n

i e @up embedywg theinventwnomprlses j notion,- With the' accompanya tubular main orbody section l and a presser cap or plug section 2. The'bodysection li may be provided with a stop flange 3 adjacentto one of its :ends and has external screwv 'threadsl elf extending from the stop flange 3 to said one end of the body forengagement Y with a threaded opening, not shown, which in actual service will lead to "'any suitable bearing.

The presser cap or plug section 2 is holvlowand is open atfits normallyinner end, thus producing a compartment 5 yWithin-the cap 'Which is in openA communicationwith ably ts'in the body l at the secondV end of Athe'latter until an annular stop flange 6 at the closed end of'the cap abut's-the adjacent or normallyputer endof the body l.

A `guiding and retaining yoke 'or frame comprises a -pair off-'parallel armsr fwvhich are connected together-at their outer ends by a cross member 8 andare joined integrally or otherwise at their inner ends to the wall's'of the body 1 lat diametrically opposite points on the' latter. Iprefer to form theiyoke integral with the' body l, the `arins i 7 vbeing prolongations of 'the Walls ofthe body at theouter end of the latter but obviouslythe yoke may be formed `separately from the body and secured to the latter in any suitableA known manner. l*

'The stop flange at "the closed end of the closurei2 is provided withl a pair of'diamet- 'rically opposite slots or notches 9? which engage with the arms 7,*Whereby theclosure 2' Will -be theld against rotation in the body 1. "H The cross member 8 serves to limit the outward movement of the closure 2 between the guides 7 and in respect to the body 1. IThe cross member 8 may be offset outwardly vintermediate itsA ends as indicated'at 10. Axiallyaligned openings lland 12 respectively are formed through the offset'portions l0 ofthe crossmember ofthe yokeand the end member orf head of the `v'closure 2.

A pull rodior stem. ,'13 may be projected rthrough the opening and may be held against axial movement outwardly or away from the closure 2 by means of a nut'll in threaded engagement with the inner-end of the pull Yrod jo'r stem. An expansion spring l5 Whichj is coiled about thejfpull stem betvve'en the *endor head of the closure and the offset portion l0 of the cross member of the yoke exertsa'pressureron'the'closure 2 llO continuously tending to slide the closure 2 in the body 1 until the stop flange 6 abuts the adjacent end of the body. The extent of inward movement of the closure 2 toward the body 1 and in response to the action of the spring 15 is adjustable by manipulating an adjustable stop nut 16 which is in engagement with the threaded portion 17 of the pull rod or stem and is disposed 0n the pull rod outwardly of the cross member 8. The pull rod or stem is provided with a head or handle 18 adapted to be conveniently grasped between the fingers of a hand when it is desired to manipulate the pull rod.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The body 1 may be attached to abearing by means of the threads 4l and cooperative threads on the wall of an opening, not shown, which leads to the bearing` or the body 1 may be permanently attached in anv suitable known manner in position to feedllubricant to the bearing. When it is desired to fill the cup`l the handle 18 is grasped and the pull rod is moved axially outwardly against the action of the spring 15 until the closure Q has been moved beyond the outer end of the Vbody 1. A suitable lubricant which is then placed in the body of the cup until the latter is completely filled and the compartment within the'closure 2 also is filled with the lubricant. The lubricant may be in the form of a stick or cakey as indicated at 19 in Figure 5 and pieces `may be severed therefrom as indicated at 20 in Figure 5 and then placed within the body of the cup and in the compartment within the closure 2. Vhen the pull rod is released7 the closure will move Vin engagement with the guide 7- until the inner or open end of the closure is inserted in the body 1 at the adjacent or outer end of the latter. Since bothtlie closure and tliebody 1 may be filled'with lubricant in the manner described, it is obvious that a cup embodying the invention and of a given Vsize will have a relatively large capacity.

The action of the spring 15 on the closure will tend to force the latter inward in the body 1 to the position shown in Figures 1 and 2 or until the stop nut 16, which is shown as being a wing-nut is in abutting Vrelation to the outer side or face ofy the offset portion 10 of the cross member 8. It therefore will be manifest that the action of the spring" 15 tends to force lubricant from the body of the cup so long as the closure is permit-ted to move inward in response to the action of the spring and that lubricant may feed by gravity from the body of the cup when further inward movement of the closure in the cup is prevented.

Obviously, vmy invention is susceptible of embodiment in forms other thairthat illustrated in the accompanying drawing and I therefore consider as my own all such modifications and, adaptations of the form of the device herein described as fairly fall within the scope of the appended claims.

I claim:

1. A lubricantcup comprising a tubular body adapted at one end for connection with a bearing or 4like support, aliollow closure slidably fitting in said body at its other end, said closure being open at its inner end and having a stop flange at its other end for engaging with the outer end of said body, said stop flange having a pair of diametri- `cal slots formed therein, guide members extending from said body at the outer end of the latter for engaging said slots, and a cross member connecting said guide inem bers at the outer ends of the latter for limiting the outward movement of said closure in respect to said body.
